The Eastwood family has a pair of titles on the list of lowest grossing studio films of 2007 compiled by Exhibitor Relations. Alison Eastwood’s “Rails & Ties” with Kevin Bacon and Marcia Gay Harden (pictured) grossed a total of just $22,136 for Warner Bros. during its two-week run at five locations — less than any other studio flick except the starless, super-obscure comedy “Full of It,” which New Line dumped on 15 screens outside NYC for a grand total of $14,237. Sadder still was the No. 3 ranking for “Grace is Gone,” a homefront war drama with John Cusack that was bought by the Weinstein Co. for a reported $4 million after it moved audiences to tears at the Sundance Film Festival. Allison’s dad Clint was so moved that he offered to write a new score to replace the original one by Max Richter. A victim of the moviegoing public’s indifference to Iraq-themed movies, “Grace is Gone” grossed a pathetic total of $36,613 during its three-week run at four locations. Other tiny grossers that have already been shuffled off to DVD after token theatrical releases: Screen Gems’ “Wind Chill” (Emily Blunt, $36,804), “Two Weeks” (Sally Field, $47,986), “December Boys” (Daniel Radicliffe, $50,715), “Home of the Brave” (Iraq again, with Samuel L. Jackson, $51,708).
